The pictured tree is in India, so is its mother. But the mother plant was from a cutting from someone who took it from around upstate NY. It thrives in India, so maybe its tropical. And was sold as an annual in NY. I thought it was Chionanthus virginicus as well. But yes I agree if you zoom into the white leaves they look different. Bromelia, I think you are right! Google images of Euphorbia leucocephala look very similar. The pictured tree seems to have thinner leaves but maybe a close different cultivar, or maybe just different growing conditions. Thanks everyone

Lithodora diffusa 'Grace Ward' for the first, I believe. The tree may be Gleditsia triacanthos var. enermis, Thornless Honeylocust.

I don't think it's invasive in the eastern US. I have one and never have seen seedlings. Some plants are invasive in certain areas of the western US but are great garden plants here.

I don't think it's Tilia henryana. Typically the "spines" of the soft spine like teeth are much longer on T. henryana than the leaves in the photo. You can find T. americana(Basswood, American Linden) with leaves with small soft "spine" like teeth like the leaves in the photo. The leaves look too large for T. henryana, which top out at about 4"x4"(10cm x 10cm), to me also. They look much closer in size to T. americana, which range from 4"x4" on the small side up to 8"x8"(20cm x 20cm), to me. Also, T. henryana in cultivation has so far been a relatively small tree in the 30' to 35' range(roughly 10m). Lastly, I'm doubtful that T. henryana(considered zone 7 hardy usually) is hardy in the zone 5 Brookfield Zoo which has seen temps as low as -20°F(-29°C) within the past 12 years or so(surely within the lifetime of this tree). So, I believe this is a Basswood tree(T. americana).
